SR-71 Blackbird

3.2 Mach

The SR-71 is a long-range, high-altitude reconnaissance aircraft developed by Lockheed Martin back in the 60's. Some 50 years later it still remains, by far, the fastest self-powered, non-rocket propelled aircraft built by man. The Blackbird's airframe is designed out the titanium to withstand the enormous heat generated at hypersonic speeds. The two crewman piloting the craft have to where fully-pressurized life-support suits, resembling those of worn by astronauts.
